## Run

This is just an experiment and the build is currently specific to Linux or WSL only

First, make sure you've set up Lean properly on your computer.
Follow the "legacy" instructions from here: https://leanprover-community.github.io/install/linux.html

Second, make sure you run the build script first to build all the dependencies to get this to work

```bash
chmod +x ./build_sdl_and_friends.sh
sudo ./build_sdl_and_friends.sh
```

Then you can run the game proper

```bash
lake exe LeanDoomed
```
